Action keys not working even when enabled

[sarahejones]

I want to use the F keys for the functions showed on them. For example, F5 to change keyboard backlight. I have been able to do this for the past 18 months with no problems, but suddenly it has stopped working. 

I have pressed F10 when starting the computer and made sure Action Keys was set to "Enabled" in the System Configuration tab and it has made no difference. They keys don't even work when pressing the Fn button at the same time. 

Can someone PLEASE offer a solution for this?
